Buying too little life insurance leaves your family short; buying far too much wastes money you could use elsewhere. Here is how to find the right number without guesswork.
The quick rule: 10 to 15x income
Multiplying your annual income by 10 to 15 gives a fast estimate. It is a reasonable starting point, but it ignores your specific debts, mortgage, and family goals - so treat it as a floor, then refine.
The accurate method: DIME
DIME is a simple checklist that adds up what your income is really protecting:
- D - Debt. Total non-mortgage debt: car loans, credit cards, personal and student loans.
- I - Income. Your annual income times the number of years your family would need support (commonly 10 to 20 years, or until your youngest child is independent).
- M - Mortgage. The full payoff balance of your home, so your family can stay without the monthly payment.
- E - Education. Estimated future college or school costs for your children.
Add a final-expense amount (often $15,000 to $25,000 for funeral and end-of-life costs), then subtract any existing life insurance and liquid savings. What remains is your coverage gap.
A quick example
Suppose you have $20,000 in debt, earn $80,000 and want 15 years replaced ($1.2M), owe $250,000 on your mortgage, and expect $100,000 in education costs. That is $1.57M, plus $20,000 final expenses, minus a $50,000 employer policy and $30,000 savings - about $1.51M of coverage needed.
Do not forget a stay-at-home parent
A non-earning parent still provides childcare, household management, and more that would cost real money to replace. Insuring both parents is usually wise.
Match the term to the need
Coverage amount is half the decision; term length is the other half. Choose a term that lasts until your mortgage is paid and your children are independent - often a 20 or 30 year term. See Term vs Whole Life for which type fits.
Review it every few years
A new child, a bigger home, a raise, or a new business all change your number. Revisit your coverage every few years or after any major life event. A free review makes this easy.
